    Abstract: A method controls an induction heating device that is configured to operate based on a multi-phase power supply and that includes a working coil configured to heat an object and a controller configured to detect the object. The method includes: receiving voltage information related to a first input voltage and a second input voltage that are supplied by the multi-phase power supply and that have different phases from each other; selecting a reference voltage among the first input voltage and the second input voltage based on the voltage information; determining a detection time point, which corresponds to a time instant at which a detection operation is to be performed for detecting the object on the working coil, based on the reference voltage; and performing the detection operation at the detection time point.
